Introduction

Circuit breakers are an important part of any industrial or residential electrical system. They protect against excess current, overvoltage, and fault current, providing safety and reliability in the event of electrical disturbances. The 8340-F410-P1K1-K3H0-8A circuit breaker is a type of miniature circuit breaker that is used in both residential and commercial settings. In this article we will discuss the application field and working principle of the 8340-F410-P1K1-K3H0-8A circuit breaker.

Application Fields

The 8340-F410-P1K1-K3H0-8A circuit breaker is designed for application in residential and commercial buildings. It is approved for building wiring systems, as well as for use in industrial applications. It is suitable for distribution systems that operate at a voltage up to 600 volts, and with a current rating of up to 100 amps.The 8340-F410-P1K1-K3H0-8A circuit breaker has a single-pole-tripping system, meaning that the breaker trips when a fault occurs on one of the three conductors, but not on the other two. This provides improved protection against overloads and short-circuit conditions. The breaker has a rated ultimate short-circuit breaking capacity of 10 kiloamperes, ensuring that it can effectively protect the system from an overcurrent condition.

Working Principle

When the normal current flowing through the circuit exceeds a certain value, the 8340-F410-P1K1-K3H0-8A circuit breaker detects the overcurrent and trips thebreaker. This action disconnects the circuit, interrupting the electrical flow and protecting the system from overloads and short-circuiting.The circuit breaker detects the overcurrent by means of an electromechanical device called a thermal-magnetic tripping unit. The tripping unit is made up of two components: a thermal element and a magnetic element. The thermal element consists of a bi-metallic strip that is heated when a certain level of current passes through it.When the current reaches a certain level, the strip expands and causes a current operated switch to close. This closes the circuit breaker, disconnecting the power supply to the circuit. Simultaneously, the magnetic element of the tripping unit becomes energized and pulls a lever, which releases the contacts and completes the trip of the circuit breaker.

Conclusion

The 8340-F410-P1K1-K3H0-8A circuit breaker is an important component of any electrical system. It can be used in a variety of applications, including residential and commercial settings, and is designed to provide reliable and safe protection against an overcurrent and short-circuiting conditions. The breaker is equipped with a thermal-magnetic tripping unit, which allows it to quickly and reliably identify and react to a current overload situation.
